Spark Plug: Application and ID

Spark Plug Type AWSF42EE (a)

(a) NOTE: Three different styles of platinum-enhanced spark plugs are produced for the 3.8L engine. Each spark plug has a different part number and use.

^ AWSF-42EG spark plugs have a platinum-enhanced ground (side) electrode and are used in cylinders 1, 2 and 3.
^ If any spark plug is removed and re-installed, it MUST be installed in the same cylinder from which it was removed.
